High-sucrose diet inhibits basal secretion of intradentinal dye penetration-stimulating parotid hormone in pigs

, 1994
Earlier studies indicated that feeding rats a high-sucrose diet for 1 wk decreases the intrinsic rate of intradentinal dye penetration in molar teeth. Because intradentinal dye penetration appears to be controlled by a parotid hormone, we investigated ...

IGF2 knockout reduces but does not abolish osteosarcoma growth in vitro and in vivo

FEBS Open Bio, EarlyView.
To test whether endogenous IGF2 promotes osteosarcoma growth, IGF2 was knocked out in Saos2 cells via CRISPR‐Cas9. KO cells showed reduced proliferation in vitro, and knockout xenografts in mice reached only ~25% of wild‐type tumor volume. Insulin‐like growth factor 2 (IGF2) is implicated in osteosarcoma, but direct functional evidence of its role is ...

APICAL MICROLEAKAGE OF VARIOUS BIOMATERIALS IN SIMULATED IMMATURE APICES

Selcuk Dental Journal, 2019
Background:: In the treatment of open apex teeth, one-step apexification has been reported as an alternative method to the use of long-term calcium hydroxide. Methods:The present study evaluated and compared apical microleakage when ProRoot MTA (Dentsply)

TRPML1 agonist ML‐SA5 attenuates pulmonary fibroblast activation by suppressing mTOR and restoring autophagic flux

FEBS Open Bio, EarlyView.
TGF‐β1 stimulation downregulates lysosomal channel TRPML1 in pulmonary fibroblasts. The TRPML1 agonist ML‐SA5 suppressed fibroblast‐to‐myofibroblast activation and collagen production. Mechanistically, ML‐SA5 inhibited mTOR phosphorylation, restored autophagic flux, and its effects were enhanced by rapamycin (mTOR inhibitor) and reversed by MHY1485 ...

Comparison of coronal sealing of flowable composite, resin-modified glass ionomer, and mineral trioxide aggregate in endodontically treated teeth: An in-vitro study

Dental Research Journal
Background: Coronal seal is one of the essential factors that affects the success of endodontic treatment and reinforces the apical seal. The intra-orifice barrier is an efficient alternative approach to decrease coronal leakage in endodontically treated

Assessment of coronal leakage of a new temporary light-curing filling material in endodontically treated teeth

Indian Journal of Dental Research, 2014
Introduction: The aim of this study was to evaluate the sealing ability of a new temporary filling material X-Temp LC (DFL, São Paulo, SP, Brazil) compared with that obtained for Coltosol (Vigodent, Rio de Janeiro, RJ, Brazil) and Vitro Fill (DFL, Rio de

Co-administered antibody improves penetration of antibody–dye conjugate into human cancers with implications for antibody–drug conjugates

Nature Communications, 2020
Antibody-drug conjugates targeting high expression receptors can suffer from poor tumour penetration. Here, the authors use unconjugated antibody to improve the penetration of an antibody-dye conjugate in a clinical study, supporting further clinical ...

Effect of Calendering and Surface Treatment on the Thermochromic Response of Cholesteric Liquid Crystals on PET Nonwovens

Advanced Engineering Materials, EarlyView.
This study explores the influences of calendering and surface treatment during direct ink writing (DIW) of thermochromic cholesteric liquid crystal (CLC) on PET nonwovens. For the PVA‐coated nonwovens, calendering reduces pore size leading to reduced ink absorption and enhanced spreading. The NeverWet‐coated nonwovens improve thermochromic responses by

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...
